Specification of Letters Patent.

Patented Jan. 8, 1907.

Application filed August II 1906. Serial No. 330,174.

To (all? whims it may concern:

Belt known that 1, JOHN B. Gear, a citizen e the United States, and a resident of the Oil of St. Louis and State of Missouri, have invented a new and useful improvement in Cloth-Cutting Machines, of which. the following is a specification.

My invention relates to cloth-cutting Ina--- chines, and has for its principal objects to minimize the friction, to minimize the pulsation, and to simplify and improve the mechanical construction.

My invention consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

in the accompanying drawings, which form part of this specification, and wherein like symbols refer to like parts wherever they occur, Figure 1 side elevation of a cuttingniachine embodying my invention, a portion of the base and standard and of the guardcase being shown in section. Fig. 2 is an elevation of theupper part of the machine looking in the direction of the arrow in Fig. 1. l 3 is a horizontal section on the line 25 3 of lfig. 1; and Fig. 4 is a sectional detail view showing the universal joint connecting the wrist-pin and the actuating-link.

The cutting-machine is mounted upon a base 1, supported on roll rs The standard 3 is mounted on the base and terminates at its top in a table 4, on which is screwed or otherwise fastened. skeleton frame 5. This skeleton frame 5 has a motor-frame 6, screwed or otherwise fastened thereto directly above the standard---that is, in alinement with the standard, so that its weight is symmetrically distributed and balanced above said standard.

The standard 3 is preferably made of a single piece and is provided with a slotor slideway 7, which serves as a guide for a knife 25. The upper and of the knife projects above the top of the standard and is secured to a rock-lmcr .l, which is pivolallj mounted in a bracket or lateral extension 1 4) ol l he skeleton frame, '\\'hvrr il y said lower or rock-arm .l is free to oscillzilc in a vertical piano.

The rock nrm .l is chum-Mod by a link H nates in a hemispherical socket having a lateral flange 14. Above the head of the Wristpin is a spherical segment 15, which is likewise provided with a lateral flange 16. j Bolts 17, extending through the flanges 14 and 16, hold the segment 15 firmly on the end of the body-piece of the link 11. A similar arrangement is used at the lower end of the link; but in this latter case the removable spherical segment is jointed along a vertical plane instead of in a horizontal plane.

It is obvious that the rock-shaft 9 may be arranged to reciprocate in a plane perpenit is preferable to have the rock-shaft 9 arranged in the same plane with the motorshaft. This latter arrangement has the great advantage of permitting a direct connectionof the wrist-pin to the rock-shaft, to which the knife is directly connected, in conparts, and those few parts (with the exce tion of the upper end of the link) are in t e same plane. The vibration or pulsatioaof the machine is therefore ver inuch reduced. The machine is manipulated by means of a handle 18, extending from the lateral bracket 10 in the plane of the movin;- arts.

fully described in applicants )ending application Serial No. 326,389,iiled July 16, 1906. The knife is kept in pro or position by means of a tensioirspring 19, astened at one end to the bracket 10 and at its other end to the knife or a not connected thereto, as more fully described in said application.

Obviously my device admits of considerable modification within the scope .of my invention, and therefore 1 do not wish to be limited to the specific construction shown and described.

to secure hylicttcrs Patent. is

l. A cloth-cutting machine comprising a base. a slandard thereon, a molor mounted on said standard, a rock-arm mounted in the plane of the motor-shaft, a link universally connected to said imuor-slml't and to said rocl\'arm, and a knife pivolally connected to said rock-arm.

2. A cloth-cutting mach-inc comprising a base, a standard thereon, a motor mounted on said standard in alincmont therewith, a rot-learn) mounted in the plane of the motordiciilar to the vertical plane of the shaft; butsequence of which there are fewer moving.

T e connection of the knife 8 to the rock? arm 9 is a pivotal connection, which is more l'l hat 1 claim. my invention, and desire shaft,.:a,'link universal lyconnected to said motor-shaft and to sand rockarm, and};

fknifegivotally connected to saidrock-arin.

reciprocating cuttingmachine com-. prising a standard having-a knife-guide therein, a motor mounted on said standard, a rock-arm pivotaliy mounted on said standard, a knife pivotaliy connected to said rockarm, and a hnk universally connected to the motor-shaft and to said rock-armj 4.
